It is never worth taking a health insurance deductible that is not CHF300 or CHF2500

Great job and comparison but is not complete. It would be interesting to include opportunity costs and tax deduction. There are cantons in which you can deductthe single costs you have from taxes and is not a ‘pauschal’ number.
For the opportunity cost, if you invest the 150 chf per month of difference you are going to have more return, particularly over 20 years etc. This could even impact other deductible making them better. Particularly in the case if you advance the money and pay everything at the beginning of the year to get some discount.

You can imagine a function like this:
y = f(x)

Then for each deductible you can draw a chart, which I did already once in this forum, July 2018 (oh how quickly the stuff gets buried here). Then you can see which deductible gives you the lowest expenses for each level of healthcare bills, which as you said, you can’t predict. And then you will notice, that the middle options are never the best.

Now when I think about it, in order to get the best deductible for you, you should try to figure out the probability distribution for your predicted healtcare bills. Then you plug it into the function for each deductible and you get the expected total cost. Maybe then the middle deductibles would start making sense? Like, what if your healthcare bills would be: 50% 0 CHF, 50% 5000 CHF. Then it would be for some years the best to take the 500 deductible, and for the others the 2500 one. But since you don’t know what to expect, maybe the 1500 one would average out as the best one? Dont’ know, would need to calculate.


It’s true that probability distributions can lead to some of the middle scenarios being best but when I explored this I found the distributions so extreme that I don’t think I would ever advocate it.

To make this work complete perhaps some modelling would be worth doing though…

I was also doing a similar analysis back in 2015 or so - so mind the differences in fees (and SWICA data)…
Breaking point was again around 1800-2000 - good to see it still holds today. :slight_smile:

However I also wanted to have a look at what happens in the extremes - if you make the worst/best possible decision.

If your expenses were zero, and you picked the lowest franchise, you would have lost (max) around 1400CHF.
If your expenses were maximum, and you picked the highest franchise, you would have lost (max) around 1100CHF.
So nothing too critical over a year, I would say.
Nevertheless, would be interesting to see the numbers today, as the costs have risen significantly.

And I continue taking the max franchise (as I am relatively young and healthy), unless I know for sure I will have a surgery or something next year (e.g. changed it for 2018, then went back).
Savings over the years would more then compensate a one year “mistake”, as per above. :slight_smile:

I think about that function with a probability parameter as well.
Let’s say that you have a probability of 73,88% of being sick for 2500 and of 26,12% of no medical bills this is how you would compare:
Deductible 300= 4450x73,88%+3930x26,12%=4314.176
Deductible 1500= 4732x73,88%+3132x26,12%=4314.08
Deductible 2500= 5017,2x73,88%+2467,2x26,12%=4351.14
So here is a mathematical valid case in with it’s worth taking an health insurance with a non-extreme deductible.

In reality that probability parameter is also uncertain. This means that you might estimate the right thing to take the 300 deductible but then you aren’t. Then next year you think that you will pay 3000 but then you pay 0. I that case it makes sense to go for a middle deductible.

To generalize:

  • if you are bad at estimating how much you are going to spend it makes sense to go for a middle deductible.
  • If you are extremly good at estimating, there are some rare cases (see above) in which it makes sense to go for a middle deductible.

I disagree with your conclusion. Unless you have something chronic isn’t it likely you will have very low cost (maybe 1 doctor visit a year, with some normal medication, flu or similar, nothing special, <300) or high cost (catch something strange, some tests, referral to specialist, more tests, expensive med). At least that is my experience.
I’ll use your odds 74 to 26, which I find quite reasonable.
That means in every 4 year period in 3 of those years I save 1400 francs, and then 1 year I pay Fr 1100 more.
Sounds like a good deal to me!
Yeah I know, bummer if the expensive period is spread over 2 calender years. You really can’t choose when u get sick (usually), but still in the positive with the max.
But it’s like investing - don’t look at one year, look at 10 or 20 years.
Max your franchise/deductible - the only option for healthy adults IMO.


There is also one thing we haven’t covered. If I have a high deductible, I am discouraged from taking care about my health. It really has that effect on me. Got a fever? Probably some cold, just stay home a few days and it will get better. Got occasional stomach pains? Doctor recommends gastroscopy for 800 chf as diagnostic, it might find something, it might not. So I don’t do it.

At some point it might happen, that you will downplay a serious disease, just because you were not sure if its worth it to visit the doctor. I remember in Poland I went much mire often to the doctor, because it was for free in my health plan.

Totally agree with that one. I switched from 2500 CHF to 300 CHF couple of years ago because of that. I rarely went to the doctor when I was sick, because I didn’t want to spend any money if it’s not something serious. But can you really always tell that?

Now I don’t really care about my medical bills. Especially after paying the franchise.

See? That’s why we are going to be like in the US in 10-15 years. People don’t care.
Don’t plan to FIRE in CH then because it will get worse and worse.


True, I think the lowest deductible should not exist, just the same one for everyone, say 2000 chf. Plus, the obligatory insurance should only cover things that most people can’t afford, that is treatments costing over 1000 chf. I don’t see why a visit at a general doctor, which costs 150 chf should be covered. And let’s be clear, I’m only talking about the scope of obligatory insurance. People could still insure for more if they pleased.

I think some things might have gotten a bit mixed up, towards the end of this conversation. So here are some points to push back a little :slight_smile:

  • Health insurers already take into account this kind of ‘bad’ behaviour you describe. Prices are set accordingly.
  • Yes, it’s probably bad for the health of a health insurance system, if you go to the doctor for every small thing. But it’s probably good for the health insurance system if you go check out that bump early, get antibiotics for your cough before you get full fledged peumonia, etc. The behaviour Bojack describes is probably good from a social welfare perspective, especially if you also take into account lost productivity from being sick. [But please don’t go to work if you are infectious :wink: ]
  • It’s a good thing that health insurers are able to provide different contracts. Insurers always want to risk select, it’s the way they can have an edge over competing firms. By only offering pooling contracts (e.g. everyone has a deductible of 2000chf) you incentivize insurers to only want to insure people with low health risks, as far as legally possible. [At the beginning of the KVG there was something similiar to that and they had to change it, if I`m not mistaken.] By allowing for seperating contracts you allow the insurers to put prices such, that people self-select towards the contract that is optimal for them. This reduces the interest of insurers to do risk selection (but it’s still there).

(The point of the OP is a fact, as far as I know. The middle contracts are just there to confuse you.)


This will only hurt the poor.

Thanks for the contribution. I’m only expressing my intuition here, it’s very possible that I’m wrong. The point about regular checkups is very good, that’s why in Singapore, where medical costs are very low, annual health checks are mandatory. If the insurance company had a long-term incentive of keeping you healthy, I’m sure they would insist on you checking your health as well. But since you can switch every year, then this incentive is not explicit.

And yes, you may be right that since there are multiple deductibles offered, the cost of e.g. Cortana going to doctor often may be fully priced into the premium of his low deductible insurance. If people abuse it, then the price difference between lowest and highest deductible should rise.

Low-taxable-income residents receive health insurance premium subsidies. In many cantons, the subsidies are higher than the cost of the cheapest available 2500-deductible health insurance. In some cantons, you actually get the difference paid back to you by the health insurance company. So in actual practice, the 2500 deductible is often the better choice for low-taxable-income residents. The only exception to this rule may be individuals who are in poor health and need a lot of medical care. The reason I use the term low-taxable-income is that you can earn a fair income and still have a low taxable income. I received health insurance subsidies for a long time because I have a large family and maxed out tax deductions. I used the highest-deductible, lowest-premium insurance available for all of us, and actually got paid the 30-franc monthly difference by our health insurance company instead of paying premiums.

For those unfamiliar with premium subsidies, check out this post on my blog:


Well, you can also say that low deductible discourage you from taking care of your health, because if going to doctor and medicine is (almost) free, then what’s the point of doing sports, eating healthy, managing stress as a means to prevent diseases? As treatment becomes cheaper, prevention is less attractive due to its high effort cost. In other words, cheap health-care (or comfort in general) can make us lazy.

In my case I’m speaking from experience, and how about your theory? I don’t think people are more willing to put their health at risk when their healthcare is covered. Smoking and drinking rates are highest in countries where healthcare is poor.

However, I’m pretty sure if the price of the premium depended on your “health score” (which would factor in obesity, drug consumption, exercise rate etc), then people would really take care of their health. The premium is a real monthly price, that you can compare with other people. Of course you don’t want to pay more, I think it could work well on psychological level.


In a funny sort of way, health insurance deductibles are a type of health score. If you have good health and expect things to stay that way, you will pick a 2500k deductible. The lower premiums are your reward for staying healthy. If you pick the 300-franc deductible, it’s safe to assume that you either have poor health or expect to. The higher premiums are your penalty for not staying healthy. In this way, health is scored in a largely anonymous way which does not discriminate or exclude, and doesn’t invade privacy.


Hi all,

Interesting post.

Does this apply to all cantons ?

Also, not quite clear, are you just comparing the Deducible + additional costs?
I can’t figure out where the monthly Premium is in the calculation. That will add up a significant amount, right ? I assume a low deductible requires a higher monthly premium
Any advice on this is appreciated.
Thank you,

The tables are including an example of premium.

It must be read like this : If you spend 100 CHF at the doctor and your deductible is 300, you spend 4030 in total. (4030 is 3930 in premium and 100 of additional cost)
